你好！
每个维基百科：相互作用星系（碰撞星系）是指其引力场相互干扰的星系。较小相互作用的一个例子是卫星星系干扰主星系的旋臂。卫星的引力可能吸引小行星的旋转臂之一。否则，卫星可能会潜入原边，从而破坏原边。
主要相互作用的一个例子是两个大星系的星系碰撞。由于大多数星系中物质的分布很微弱，所以这些碰撞不像是正面碰撞，而是更多的引力相互作用。

美国天体物理学家Halton Arp，（1927年至2013年），1949年毕业于哈佛大学，并于1953年获得加州理工学院的博士学位。1957年，他成为帕洛玛天文台的一名工作人员，并在那里工作了29年。后来，他于1983年加入德国慕尼黑附近的马克斯·普朗克天体物理学研究所。
在加州理工学院期间，他开始“收集”不寻常的星系，其他研究人员认为它们太不寻常或太奇特而从他们的研究中消失。阿尔普认识到这些奇异的星系代表着星系演化的不同阶段，并致力于利用200英寸的黑尔望远镜研究它们以及相关的准星体（QSO）。
最终，这使他挑战了当前对某些高度红移的资料的解释，甚至对“大爆炸”理论提出了质疑。在2013年去世之前，Arp继续持相反观点，并在大众文学和科学文献中发表了他的研究。如今，随着现代天文台摄像机和太空望远镜的问世，结论性研究已经证明Arp固有的红移的“反理论”是不正确的。但是，尽管最终证明他是错的，但由于对公认理论的强烈挑战，霍尔顿·阿尔普为天体物理学做出了重大贡献，迫使其他天文学家重新验证了他们关于星系形成和宇宙学的假设。
Arp的地图集也已成为高级业余天文学家寻找深空观测/成像项目的有用工具。
业余天文学家会在星图集和观测指南中找到许多“ Arp”天体，它们分别是NGC，IC和UGC星系。

阿尔普（Arp）编制了一份名为《奇异星系地图集》的不寻常星系目录，该目录于1966年首次出版，其中包含338个附近星系的照片，这些照片均未属于任何经典的银河系类别。现在，Arp的地图集被公认为是相互作用和合并星系的极佳汇编。
2006年，Amatuer天文学家Jeff Kanipe和Dennis Webb将Arp的地图集扩展为观察者指南，其中包括Arp的原始图像，取景器图和CCD图像以及来自其他参与的业余爱好者的视觉观察。
这是一本在野外使用的好书！

此外，还有一些很棒的在线资源。
阿马里洛天文学俱乐部的业余天文学家鲍勃·希尔（Bob Hill）汇集了他的最佳观测站点，按季节列出了100个最佳Arp星系。您可以在这里找到第一部分： 游览特殊的宇宙：
苏格兰业余大卫·理查兹（David Richards）有一个很好的站点，可以从他的天文台看到它： 大卫的天文学页-ARP特殊的星系：
另外，业余爱好者阿尔文·休伊（Alvin Huey）有一本很好的观测书您可以购买他的网站。
（他也有许多免费下载！！） faintfuzzies：
最后，您可以在以下位置在线找到Halton Arp博士的地图集的PDF： PLASLIAR GALAXIES：以下是我对“特殊星系Arp地图集”的个人观察清单。
目前，我在宾夕法尼亚州匹兹堡纬度+40左右的338个对象中有106个可见。
我所有的图像都是使用StellaCam-3珀耳帖冷却的Deepsky摄像机拍摄的。每幅图像都应用了最少的处理：调整亮度/对比度，旋转图像以匹配Arp Atlas书本的图像，并调整大小以在图像上具有相同的总体视场大小。然后，我制作了一个带有红色线条的负“查找器图”，该红色线指示了特殊情况的一般位置。
